7 Claims.

This invention relates to an apparatus for arranging fabric in kiers ortanks, which apparatus is more commonly known as a kier piler.

necessary that the of a rope be piled ough and even treatment of thecloth in its entirety.

It is the purpose of this invention to provide a simple and improvedkierpiler.

A better understanding of this invention will be had from considerationof the following drawings in connection with the following descriptionand in which;

Figure 1 is a side elevation of a kier piler constructed in accordancewith the invention and is illustrated in position over a kier;

Figure 2 is an end elevation of the same kier piler;

Figure 3 is a side elevation of to that shown in Figure 1;

Figure 4 is an enlarged detail of the cam and associated parts; and

Figure 5 is a sectional detail of slip ring construction.

As can be seen from the side opposite operating the bearing and thedrawings, the entire apparatus is supported upon cross beams I whichspan the kier. These cross beams can be at any desired point above thekier, although for con- Figure 1 shows the cross mounted or travel upontracks (not shown) positioned above the kiers to be served by theapparatus.

The kier piler itself consists of a feed tube or conduit 3 into whichthe fabric 4 in rope form is fed by any suitable means. Tube 3 issupported rotatably by a combination journal and thrust bearing 5,illustrated in more detail in Figure 5, and which retains the tubeagainst downward movement while permitting rotation about itslongitudinal axis. It will be understood that any standard type ofbearing capable of supporting the tube for rotation and carrying thevertical thrust may be employed; The fabric to be treated and piled inthe kiersis fed through the entire length of the tube which serves as afeeding means for conducting the fabric to a main drum or pulley l,rotatably supported by suitable bearings, in brackets 8 depending from atable or support 9, carried bythe lower end of tube 3 was to berotatable therewith.

The entire assembly so far describedis rotatable about a vertical axisand specifically the axis of the tube 3 and is positively rotated in thebearing 5 by means of a motor H driving reduction gearing l3 terminatingin pulley l5, all cararcund drum 7 then rotatably supported by the arms23, also depend ing from the table 9, and then back to and around drum5. axis in lined relatively to the axis of drum 1 so Although thevelocity and weight of the rope of fabric is sufficient to rotate drum1, it is preferred to positively drive The tangent roll is spring urgedor into contact By oscillating loaded with the drum 1 by springs-45.

arms 43, the position of tangent spirit and scope of the invention as 2roll 4| may be varied about the periphery of drum 1 and accordingly thepoint of departure of the fabric 4 from drum 1 may be varied dependingupon the position of roll 4|. This and the velocity of travel of thefabric will determine the manner in which the fabric is piled in thekier. In order to vary the position of the tangent roll 4|, andcause thefabric to be piled as illustrated in Figure 1, one of the arms 43 isconnected by a link 41 to one end of an arm 49, the other end of whichis secured to a cam follower shaft 5| which is also rigidly fastened tocam follower 52 which engages a heart-shaped cam 53 secured to cam shaft54. Cam shaft 54 also carries a pulley 55 driven by a belt 56 engaging apulley 51 on the drum shaft. The linkage and. cam just described forvariably positioning the tangent roll isso designed as to cause propermovement of arms 43 and tangent roll M as to cause the fabric to bepiled radially of the kier; one form of piling being shown in Fig. 1. Asthe entire unit is rotated the fabric will be piled over the entire kierfloor. Obviously different cams and linkage can be employed to cause adifferent throw of the fabric.

From the foregoing, it will be seen that as a rope of fabric is fed intoconduit 3 it descends through the conduit and engages drum 1, taking onecomplete turn therearound passing under tangent roll 4| which throughheart-shaped cam 53' controls; the point of departure of the fabric. Theposition of tangent roll 4| is constantly varied as the entire device isrotated about the axis of conduit 3 thus causingv the cloth to be piledevenly and throughout the entire kier without tangling. It can also beseen from the foregoing that inherently the foregoing mechanism can beused to pile the fabric in the kier in at least two ways, If the lineartravel or velocity of the fabric, in feet per second for example, isequal to the product of the number of complete oscillations per secondof the tangent roll and twice the radius (i. e., the diameter) of thekier, the fabric will be laid or folded as shown diagrammatically inFig. 1. On the other hand if the velocity of the fabric is greater, thefabric will be piled substantially evenly over the entire kier floor asbefore, but the fabric will be in bunched or crowded radial folds ratherthan in folds or layers ofa single thickness or lamination. Theforegoing mechanism is comparatively simple in construction andcomparatively light in weight so that it is portable and can readily bemoved from one kier to another.

It, will be obvious to those skilled in the art that minor changes maybe made in the details of construction without departing from thedefined in the appended claims.
